类氦等电子系列离子的双电子复合速率系数

给出了一套计算类氦等电子数系列离子双电子复合速率系数的解析公式，这套公式能快速、准确地给出类氦离子从Ｂ３＋到Ｘｅ５２＋、电子温度在０．１ｋｅＶ到７０ｋｅｙ范围内各离子的双电子复合速率系数。作为一个例子，计算了类氦硅离子双电子复合速率系数，并与Ｋａｒｉｍ等人的理论从头计算的结果作了比较，二者十分一致。

Dielectronic Recombination Rate Coefficients for He-like Ions

We derived a set of analytic rat6 coefficients formulas for dielectronic recombination of He- like ions. By these formulas the dielectronic recombination rate coefficientS may be calculated accurately and rapidly without the necessities of doing full ab initio calculations. As an example, we have calculated the rate coefficients of He-like Si ion, and compared with the explicit calculations made by Karim et al., yielding an excellent agreement.
